成物に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a masterbatch resin composition. More specifically, it is used for simple coloring of styrene resins such as acrylonitrile / butadiene / styrene copolymer resin (ABS resin) as a natural resin. The present invention relates to a masterbatch resin composition that is mixed and has good dispersibility.

Description of the Related Art For coloring a thermoplastic resin, a powdery dry color prepared by mixing a pigment and a dispersant, a liquid color or a paste color prepared by dispersing a pigment in a liquid dispersant at room temperature, or a solid color at room temperature. There are pellet-like, flake-like, or bead-like masterbatch resin compositions in which a pigment is dispersed in a resin.

などが挙げられる。These coloring compositions are properly used depending on the application, but among them, the masterbatch resin composition is preferable from the viewpoints of easy handling and preservation of working environment during use. It is used in And, the performance required as a masterbatch resin composition is also high in the conventional pigment content, and in addition to being excellent in pigment dispersibility, heat resistance of the thermoplastic resin to be colored, strength, etc. It can be mentioned that the effect on various physical properties is small.

点があり好ましくない。In order to satisfy that the pigment content is high, the pigment content in the masterbatch resin composition has been simply increased. However, this method makes it difficult to disperse the pigment, and uneven color appears on the surface of the molded article. Is likely to occur, which is not preferable. In order to increase the pigment content and improve the dispersibility, and to prevent the color unevenness of the molded product, the melt viscosity of the masterbatch resin composition is lowered to lower the melt viscosity of the base resin of the masterbatch than that of the thermoplastic resin to be colored. Even lowering was done. However, this method is not preferable because it has a drawback that the mechanical strength and heat resistance of the masterbatch itself are lowered, and various physical properties such as heat resistance and strength of the thermoplastic resin to be colored are lowered.

困難であるという欠点を有している。For example, in JP-A-63-113057, a thermoplastic resin having a very high fluidity is used as a thermoplastic resin to be mixed with a masterbatch resin composition, and a polyethylene wax, a polypropylene wax, a fatty acid metal salt or the like 1-2 is used. A method of making a masterbatch containing one or more pigment dispersants is disclosed. However, since the masterbatch resin composition obtained by this production method is extremely rich in fluidity as compared with the raw material resin in which the thermoplastic resin compounded in the masterbatch resin composition is widely used, it adversely affects the final molded product, It has a drawback that it is difficult to obtain a molded product having physical properties equivalent to those of resin (for example, reduced mechanical strength and heat resistance).

ない。The present invention will be described below. In the present invention, an acrylonitrile-styrene copolymer resin having a solution viscosity of 5 to 15 CPS, preferably 7 to 12 CPS as measured by the Ostwald-Cannon-Fenske capillary method described below is used. When the solution viscosity of the acrylonitrile / styrene copolymer resin as the resin composition for masterbatch is less than 5 CPS, the mechanical strength of the masterbatch itself becomes low and the production of the masterbatch resin composition becomes difficult, which is not preferable. If the solution viscosity exceeds 15 CPS, the compatibility with the thermoplastic resin to be colored becomes poor, resulting in poor dispersion of the pigment and uneven color, which is not preferable.

A resin in which the proportion of the unsaturated nitrile compound in the acrylonitrile / styrene copolymer resin is less than 20% by weight is not preferable because the mechanical strength and heat resistance are low. On the other hand, if it exceeds 50% by weight, the heat resistance is improved, but the kneading property with other resins becomes difficult, which is not preferable.

If this value is less than 10 times, the pigment concentration of the masterbatch resin composition becomes small, which is not economical.
On the other hand, if it exceeds 50 times, it becomes difficult to disperse the pigment unless a lubricant or a plasticizer is added, and color unevenness is likely to occur on the surface of the molded product, which is not preferable.
